I use a FP for some small batches of dough. The friction of the blade does
cause the dough to get warm, fast. I agree it isn't caused by heat from the
FP motor. You can start with cold liquid if this is a problem. One way to
mitigate the heating is to add the liquid until the dough consistency if
right and then let the dough rest for about 10 minutes. Then you can turn
the machine back on to knead. I let the dough ball rotate about 50 times,
or about 1 minute. More than that and the dough gets too hot.
